Apple Pascal
open-in-new
<p>Apple Pascal is an implementation of <a href="/facts/Pascal_/b3yvp8bF">Pascal</a> for the <a href="/facts/Apple_II/se82CNvK">Apple II</a> and <a href="/facts/Apple_III/JcGuVETr">Apple III</a> computer series, based on <a href="/facts/UCSD_Pascal/xxmwFYV5">UCSD Pascal</a>. Just like other UCSD Pascal implementations, it ran on its own <a href="/facts/Operating_system/8XTuvMh2">operating system</a> (<i>Apple Pascal Operating System</i>, a derivative of <i>UCSD p-System</i> with graphical extensions). </p><p>Originally released for the Apple II in August 1979, just after <a href="/facts/Apple_DOS/1hUpsAzu">Apple DOS</a> 3.2, Apple Pascal pioneered a number of features that would later be incorporated into DOS 3.3, as well as others that would not be seen again until the introduction of <a href="/facts/Apple_ProDOS/51vuP5te">ProDOS</a>. </p><p>The Apple Pascal software package also included disk maintenance utilities, and an <a href="/facts/Assembly_language/7XuV0cla">assembler</a> meant to complement Apple's built-in "monitor" assembler. A <a href="/facts/Fortran/m1KqjcMU">FORTRAN</a> <a href="/facts/Compiler/WNfCDFJe">compiler</a> (written by Silicon Valley Software of <a href="/facts/Sunnyvale%2c_California/ghnntvr1">Sunnyvale, California</a>) compiling to the same <a href="/facts/P-code/EPkMFR7M">p-code</a> as Pascal was also available. </p>
